The SuperDuty 300 is truly the ultimate reel for big bait, heavy line, big fish situations around the country and around the world. You spoke, we listened. The SuperDuty 300 is a supersized version of the original SuperDuty, with increased line capacity and overall brute strength. The 300 was made for fishing 8-10 swimbaits for double-digit bass, topwater fishing for Yellowtail off the coast of California, and targeting Muskie; the fish of 10,000 cast. The search for a reel that can withstand the hardest fighting freshwater fish in the world is over.
